# Light Phone III
The **Light Phone III** is a minimalist 5G mobile phone made by The Light Phone Inc., a Brooklyn, New York company founded by Joe Hollier and Kaiwei Tang, designed to provide calls, texts, and a small set of utility tools while excluding web browsing, social media, email, and third-party apps.

## Purpose and design philosophy
Light positions the phone as a tool to reduce screen time rather than a full smartphone replacement. Co-founder Joe Hollier has said what defines the product is what it will never have: internet browsing, social media, email, and news feeds of any kind.[2](https://www.fastcompany.com/91549434/is-the-light-phone-getting-too-smart) The company's design manifesto for the third model identified texting as the priority, because the small, slow [E Ink](https://www.edgepedia.org/e-ink) screen of the Light Phone II was a hurdle for many users; the fix was a larger, more responsive AMOLED panel with more width for the keyboard.[9](https://www.thelightphone.com/blog/light-iii-design-manifesto) Light's CEO Kaiwei Tang told [The Verge](https://www.edgepedia.org/the-verge) that the E Ink screen had been the number one reason people abandoned their Light Phone.[10](https://news.halloffame.workers.dev/reviews/637178/light-phone-iii-review-minimalist-smartphone)
The interface keeps almost everything monochrome and unenticing; the screen shows color only when the camera is open.[4](https://support.thelightphone.com/hc/en-us/articles/360030784132-Display-Screen-Light) • [10](https://news.halloffame.workers.dev/reviews/637178/light-phone-iii-review-minimalist-smartphone) A rotating wheel on the left side controls screen brightness and, when pressed, turns on a flashlight.[4](https://support.thelightphone.com/hc/en-us/articles/360030784132-Display-Screen-Light)
## Hardware
The phone is a small rectangle, 106 mm tall and 71.5 mm wide and 12 mm thick, weighing 124 g.[3](https://www.thelightphone.com/light-phone-iii-specifications) • [11](https://www.engadget.com/mobile/smartphones/light-phone-iii-review-minimalism-stretched-to-the-point-of-frustration-141559294.html) Inside are a Qualcomm SM 4450 chipset, 6 GB of RAM, and 128 GB of storage.[3](https://www.thelightphone.com/light-phone-iii-specifications) The 1800 mAh battery is replaceable behind four screws on the back, and the screen and USB port can also be replaced, a repairability improvement over earlier models.[1](https://techcrunch.com/2025/03/13/minimalist-light-phone-iii-launches-march-27/) • [6](https://www.wired.com/review/light-phone-iii/) The trade-off for the removable battery is an IP54 rating, which covers limited dust exposure and water splashes from all directions but not submersion.[5](https://support.thelightphone.com/hc/en-us/articles/360030781732-Exposure-to-Liquids-Dust)
This is the first Light Phone with a camera: a 50 MP rear sensor whose images are binned to 12 MP output, and an 8 MP front sensor for selfies.[3](https://www.thelightphone.com/light-phone-iii-specifications) • [11](https://www.engadget.com/mobile/smartphones/light-phone-iii-review-minimalism-stretched-to-the-point-of-frustration-141559294.html) A two-step camera button on the lower right opens the camera from anywhere in the operating system, with a half-press triggering focus.[12](https://support.thelightphone.com/hc/en-us/articles/36100487624980-Light-Phone-III-Introduction) • [6](https://www.wired.com/review/light-phone-iii/)
## Software and tools
The phone runs LightOS, a custom interface on a stripped Android base, with no app store, no browser, and no social media.[10](https://news.halloffame.workers.dev/reviews/637178/light-phone-iii-review-minimalist-smartphone) • [13](https://finite-resources.com/articles/dumbphone-showdown-2026/) At launch it shipped with a basic alarm, camera, and album tool pre-installed, and the full tool set grew to include Phone, Calculator, Calendar, Directions, Directory, Hotspot, Music, Notes, Podcasts, and Timer.[12](https://support.thelightphone.com/hc/en-us/articles/36100487624980-Light-Phone-III-Introduction) • [6](https://www.wired.com/review/light-phone-iii/) Tools are added or removed through Light's Dashboard website, which also manages contacts and Light SIM activation; every additional tool is optional.[12](https://support.thelightphone.com/hc/en-us/articles/36100487624980-Light-Phone-III-Introduction)
The Directions tool is powered by Here and provides driving, walking, and public transit directions on a monochrome map.[6](https://www.wired.com/review/light-phone-iii/) Music and podcasts are not streamed; audio files are loaded onto the phone through the web dashboard.[13](https://finite-resources.com/articles/dumbphone-showdown-2026/) Software updates arrive wirelessly and regularly; the change log shows near-monthly LightOS releases for the III, adding features such as audio messaging, gesture navigation, a mobile data toggle, eSIM support in beta (December 2025, not yet working with Verizon), and, in July 2026, the first Weather and [Authenticator](https://www.edgepedia.org/authenticator) tools built with the company's new software development kit.[7](https://support.thelightphone.com/hc/en-us/articles/360031105751-Software-Versions-Change-Log)
The Authenticator tool matters practically: because there is no app store and never will be, banking apps cannot be installed, and the built-in authenticator for time-based two-factor codes is one of the few ways to handle app-based logins on the device.[14](https://www.banthebots.org/explainers/what-dumb-phones-can-and-cant-do) In 2026 Light opened a software development kit allowing external developers to build tools in Kotlin, subject to review, signing by Light, and restrictions on which Android APIs may be used.[15](https://github.com/lightphone/light-sdk/blob/main/README.md)
## Connectivity and carriers
The Light Phone III is a 5G phone that requires a 5G data plan from a compatible carrier, with fallback to 4G where 5G is weak or absent.[16](https://support.thelightphone.com/hc/en-us/articles/11665241683860-Carrier-Questions) There is a single global hardware version, unlike the regional Light Phone II, and in the United States it is certified on T-Mobile, Verizon, AT&T, Boost, Mint, Ting, and US Mobile.[6](https://www.wired.com/review/light-phone-iii/) At launch, new Verizon SIMs could not be activated directly on the phone; users had to activate on another device first.[12](https://support.thelightphone.com/hc/en-us/articles/36100487624980-Light-Phone-III-Introduction) The device is identified in FCC filings as model TLP301 under FCC ID 2AIBC-GOLIGHT3, manufactured by Shenzhen Futaihong Precision Industry, a Foxconn factory.[17](https://device.report/m/5bbb080b75a7b328d228145f6addafb8c49e874bb3cb58989b6287a085cb6102)
## Reception
Reviews in March 2025 were broadly positive about the hardware and divided on daily usability. WIRED rated it 8 out of 10, calling it a significant hardware upgrade over its predecessor and praising the responsive OLED screen, call quality, and stereo speakers, while flagging the $599 price and inactive features such as the fingerprint sensor and NFC tap-to-pay.[6](https://www.wired.com/review/light-phone-iii/) The Verge scored it 7 out of 10, calling it the most impressive Light hardware yet but noting that the NFC sensor, video chat, and fingerprint reader were not yet active.[10](https://news.halloffame.workers.dev/reviews/637178/light-phone-iii-review-minimalist-smartphone) Engadget found the camera's shutter lag of one to three seconds disqualifying for moving subjects and the absence of autocorrect a serious obstacle to texting, concluding the phone was not ready to be most people's only device.[11](https://www.engadget.com/mobile/smartphones/light-phone-iii-review-minimalism-stretched-to-the-point-of-frustration-141559294.html)
## Sales and context
More than 20,000 Light Phone III units had sold by early 2026, when demand outpaced supply and customers had to pre-order and wait.[2](https://www.fastcompany.com/91549434/is-the-light-phone-getting-too-smart) Shipping began March 27, 2025 after regulatory certification ran two to four weeks behind schedule, and the company later announced an eight-week pause in shipments.[18](https://www.thelightphone.com/blog/beta-testing-and-mass-production-kickoff) • [19](https://www.linkedin.com/posts/tangkaiwei_yesterday-we-announced-an-8-week-pause-in-activity-7316548672542908416-CJPa)
The phone has found a niche among adults seeking digital detox and among parents and schools; Light distributed phones to all students and faculty at the Buxton School, a boarding high school in Massachusetts, beginning in fall 2022, and the device is marketed as a first phone for children, with tools addable only through a parent-controlled dashboard.[2](https://www.fastcompany.com/91549434/is-the-light-phone-getting-too-smart) • [20](https://support.thelightphone.com/hc/en-us/articles/360030790292-Parents-Giving-Light-Phone-to-Children) The broader market remains small: market intelligence firm IDC counted just over 4 million dumb phones in American hands in 2025 against more than 130 million smartphones.[2](https://www.fastcompany.com/91549434/is-the-light-phone-getting-too-smart)
